I'am very new to motorized biking yesterday I was riding and got home to find out when I stopped from riding that the bike would not move again (back tire) Usally I hit the clutch and It moves but now It won't react to the clutch although the clutch arm Id moving I keep hearing about this ball bearing that goes behind my rod inside my front sprocket in dont have one but It was working just fine without also when I move the bike the tire will spin about 1/10ths a revolution and the engine will make a noise any ideas on where to start?? Also my chain seems to not be greased but it is aligned and i cant even pedal the back because it wont react to the clutch thanks

open drive sprocket cover & clutch cover and look to see why/where spinning stops

I opened the sprocket cover and the bikes chain will have slack when i push it forward but itll stop as the back tire moves forward itll stop as the chain tightens around the sprocket i have no clue also the engine is making a slight chugging noise when i push it forward

drive sprocket has a chain and a shaft - clutch has two parts and a shaft

you need to look there when moving bike and see where movement stops

I dont know how or where to start with the clutch shaft can u send a pic or explain more but like I said actuator bearing Is missing from the sprocket can this be why it isnt reacting to clutch

Can YOU post a pic of each side with the covers off (nothing else off!)? And one of the clutch cam? ;)

The clutch SHOULD not work with the ball bearing missing. How it did used to work I cannot explain.. I have been trying to figure it out from just these two details, and I think it may kind-of work temporarily if the flower nut is way too far out (6mm+, right on the end of its threads) but we'll see what your pictures show.

Having no ball bearing would transfer the rotation to the bucking bar/clutch cam
_and wear it away very quickly_.
Once the cam is gone: no more seperation, so the clutch doesn't even kind-of function anymore.

If this is the case you would need to replace the clutch cam (might be easier to buy the whole cover/cam/arm assembly in one) and probably the bucking bar, and definitely get yourself a 6mm ball bearing. You will have to reset the clutch, with the flower nut in a normal position.
